Abstract

L'invention concerne un procédé de détermination de l'axe de rotation et du centre de rotation d'une roue de véhicule au moyen d'au moins deux unités de prise de vue associées l'une à l'autre en position et en situation pendant le déplacement du véhicule, et un dispositif d'évaluation postérieur à celles-ci traitant les informations d'image enregistrées, avec l'intégration de plusieurs caractéristiques de roue (10) présentes sur la roue ou appliquées pour la mesure, et d'au moins une caractéristique de carrosserie présente sur la carrosserie ou appliquée pour la mesure. Des coordonnées 2D des caractéristiques de roue (10) et d'au moins une caractéristique de carrosserie sont enregistrées de façon synchrone. De là, leurs coordonnées 3D sont calculées à certains intervalles de temps, puis recalculées à un instant de référence déterminé auparavant ou à une position de référence correspondante de la roue de véhicule en tenant compte du trajet parcouru par rapport à la position de référence par la au moins une caractéristique de carrosserie. L'invention vise à obtenir des résultats de mesure les moins erronés possibles, en particulier lors d'un déplacement sur une chaussée réelle. À cet effet, lors de l'évaluation d'une analyse concernant les répercussions, les parties courbes des caractéristiques de roue (10) et de la au moins une caractéristique de carrosserie sont soumises à au moins un des facteurs d'influence suivants : angle de braquage, mouvement de braquage, déformation de la chaussée, changement de vitesse. De plus, l'analyse permet de déterminer des valeurs de correction ou des fonctions de compensation résultent pour corriger les répercussions.
